This rolling gear bag from M-Rock is for getting gear from home to dock and dock to boat without breaking a sweat - and without compromising the safety of sensitive stuff like still and home-video cameras and electronics. Backpack straps, plus a contoured back pad, make it as comfortable to tote over rough ground as it is easy to roll to the distant end of B-dock. Silicone wheels won't pick up debris or scratch the deck, and stainless-steel ball bearings give it durability to serve in marine environments. Individual dividers are padded and moveable to customize the bag. A removable pullout bag can be used to carry personal items like a towel or swimsuit. Worried that rain or wake spray may dampen your gear? Pull out the stowaway rain fly and wrap it in its own protective coat. $290; www.m-rock.com
